Questions of this type are tricky and it would be better to show an approach in finding the answer, rather than just quoting the answer.

My approach to this question :

Multiply the numerator with 10, which gives

=> 230/24 = 115/12 = 9.58333..

This shows that the number 3 is repeating and hence the 23rd decimal.

You may divide the result with 10, yielding 0.983333.., which is the correct result for 23/24.

Since 23/24 = 0.95833..., then the 23rd digit to the right of the decimal point of the decimal equivalent of the fraction is 3.

23/24 can be represented in decimal form as 0.958333333333
As we can see after 3 decimal places digit 3 is getting recurring
so the twenty-third decimal to the right in the fraction 23/24 is infact 3
Correct answer - C

Bunuel, Is there any shortcut to solving problems like this instead of going through the division itself?
